Transition path sampling in organometallic catalysis: Overcoming the rare event problem in ab initio molecular dynamics
Creators: name: Rowley, Christopher N

Year: 2010
Subjects: subject: Chemistry, Molecular.

description: Since the advent of density functional theory (DFT), computational modelling has become a widely-used tool in organometallic chemistry. This modelling is typically limited to identifying the minima and transition states on the potential energy surface (PES) of a reaction and calculating free energies using the harmonic approximation. Ab initio molecular dynamics (AIMD) is an obvious strategy to address these issues. Within these simulations, the full range of thermally accessible structures is explored and anharmonicity is expressed intrinsically. As AIMD simulations are computationally demanding, the maximum length of a simulation is on the order of 100 ps. It is exceedingly rare for a chemical reaction to occur within this time scale, which precludes the use of straightforward AIMD simulations to study organometallic reaction dynamics or to calculate free energy barriers. We attempt to resolve this time scale limitation by adapting Transition Path Sampling (TPS) for use in organometallic chemistry. TPS is a novel Monte Carlo technique to focus an MD simulation on a reactive event. We present new algorithms to generate initial reactive trajectories for TPS and a novel trajectory generation algorithm which uses a variable perturbation size to improve the sampling efficiency. Our first path sampling study investigated the Ru---hydride catalyzed H2hydrogenation of olefins We identified non-RRKM behaviour of the elimination step of a critical reaction intermediate of the hydrogenation catalytic cycle. Through a spectral decomposition of the vibrational energy, we determined the non-RRKM behaviour results from a localization of vibrational energy in the reactive modes of this intermediate following the rate-limiting insertion step. Our second TPS study modelled the beta-hydrogen transfer chain termination reaction of a zirconocene polymerization catalyst. The reaction dynamics showed that the barder of the e-hydrogen transfer is atypically flat due to a Zr---H interaction in the transition state. We subsequently used AIMD to study the equilibrium structure and beta-hydrogen transfer free energy profile of this system with and without a counteranion present. These simulations showed that the counteranion-dipole interactions have a significant impact on the preferred configuration of the catalyst and the free energy profile of the transfer.

description: The purpose of the research work (in partnership with the Ontario Geological Survey (OGS) and International KRL Resources Corp. (KRL)) was to better define the geology and mineralization of the Big Four Lake area, close to Shining Tree in Ontario, part of the southwesthern Abitibi greenstone belt. Rocks of the area belong to the Deloro assemblage a suite of calc-alkaline mafic to felsic metavolcanic rocks, tholeiitic mafic to intermediate metavolcanic rocks, iron formation plus komatiites of the Kidd-Munro and Pacaud assemblages, all cut by later intrusions. The rocks are metamorphosed to the greenschist facies and for the most part are only slightly deformed. A 1:10,000 scale geological map was produced in order to characterize the distribution of Deloro assemblage rocks and the Proterozoic intrusions. Seven different units were defined: (1) Mafic to intermediate metavolcanic rocks, (2) South rhyolite, (3) Volcanoclastic rocks, (4) Red Dome rhyolite, (5) Sulfide---rich chemical metasedimentary rocks, (6) Matachewan dike swarm, and (7) Nipissing gabbro. Major and trace element geochemistry shows that unit 1 rocks are tholeiitic whereas units 2 and 4 are calc-alkaline. Accordingly the Deloro assemblage rocks (units 1 to 5) are interpreted to have formed in a back-arc setting. The mafic to intermediate metavolcanic rocks have affinities with N-type MORB and a volcanic-arc environment. In the field, the Red Dome rhyolite has a characteristic hematization whereas the South rhyolite is strongly sericitized and has conspicuous alkali feldspar phenocrysts. Based on the presence of columnar jointing, autoclastic fades, and its massive form, the Red Dome rhyolite is interpreted to be a dome. The South rhyolite was earlier interpreted to be pyroclastic because of the presence of pumice fragments in a breccia that surrounds massive facies. However, there is no evidence of explosive and hot emplacement, and there are red chert clasts within the breccia which is itself located close to a conglomerate containing fragments of the South rhyolite. Because these two facies surround massive rhyolite, the South rhyolite is also interpreted to be a dome. Mineralization is characterized by pyrite, chalcopyrite, magnetite, hematite, malachite in quartz and carbonate veins that cut the Red Dome rhyolite. Exploration in the area focused on this mineralization because it was thought to be a VMS environment. The chlorite mineral chemistry is relatively iron-rich consistent with a metamorphic rather than hydrothermal origin and the rhyolites are not the Fill type typical of VMS. It is concluded that the mineralization may have been hydrothermal, possibly from a small, or aborted, VMS system, or related to later regional felsic intrusions or even the Proterozoic intrusions, which may have provided heat to remobilize metals.

description: The estimation of chlorophyll content is an essential biochemical parameter to track the main developmental stages and yield of cereals relevant for precision agriculture. Traditional techniques for chlorophyll content measurements are time consuming, expensive and laborious. Measurements at field level have proven to be a good alternative, but their use is limited due to extensive sampling designs and techniques. Several spectral chlorophyll indices have been developed to estimate chlorophyll content both at the leaf and canopy level using remote sensing data. A methodology of using spectral chlorophyll indices to estimate chlorophyll content from laboratory and satellite hyperspectral data was carried out in this study for wheat crops. The application of this technique under agricultural field conditions has been very limited and not rigorously validated for wheat crops. The main objective of this study is to validate the chlorophyll content estimation using spectral chlorophyll indices, and to examine the potential for chlorophyll content estimation using hyperspectral remote sensing data in the context of precision agriculture.

Les officiers de milice Canadiens sous le régime Français: Étude institutionnelle et sociale

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2004
Subjects: subject: History, Canadian.

description: Au Canada du XVIIe siècle, la milice émergea comme institution d'encadrement pour une population qui devait prendre en main sa propre défense. C'est l'institution parallèle des officiers de milice, et plus particulièrement l'exercice de leurs fonctions sous le Régime français, qui constitue l'objet de cette thèse de maîtrise. Si l'on s'en tient à l'ensemble de la période et à l'ensemble du corps, ces hommes sont actifs à la fois sur le plan militaire et sur le plan administratif. Cependant, dans la mesure ou l'activité de chaque officier ne fut pas identique, il faut nuancer cette généralisation et prendre en considération l'évolution de la charge dans le temps et dans l'espace. Les fonctions des officiers des milices locales, organisées ici et la dans la colonie à partir de 1648, ainsi que de ceux de la milice régularisée après 1669, furent surtout militaires. Des développements ultérieurs, notamment l'envoi des troupes de la Marine dans la colonie, la professionalisation militaire de la gentilhommerie canadienne, ainsi que le climat de paix qui s'établit au début du XVIIIe siècle, eurent comme effet de reléguer ces officiers à un rôle subalterne. Néanmoins, leur corps conserva une place fondamentale dans l'appareil offensif, mais surtout défensif, de la colonie jusqu'à la fin du Régime. (Abstract shortened by UMI.)

Agricultural women in struggle movement

Subjects: subject: Women's Studies.

description: The main objective of the thesis is to investigate the complex and, sometimes, contradictory relationship between women's activism, feminism and the deployment of feminine identities. I did so by examining the actions, strategies, and discourses of an innovative rural women's movement that emerged in Argentina in the mid nineties: the Movimiento de Mujeres Agropecuarias en Lucha (MML). This thesis looks at the changes and transformations that participation in the MML caused in MML women's lives. First, I seek to understand how, and to what extent, the participation in the movement politicized MML women's everyday lives. Secondly, I examine the effects of women's participation in the MML on the socially constructed representations of "feminine roles" and on the social relations of gender in rural Argentina. Lastly, I focus on how it would be appropriate to position the MML, a women's movement, vis-a-vis feminism. By analyzing secondary data and ten in-depth interviews with leaders of the MML, I conclude that their participation in the MML has politicized MML women's everyday lives; it has challenged and, to some extent, changed their socially constructed representations of feminine roles (as being solely those of mothers or wives) and social relations of gender (that exclude women from public policy making). While MML leaders rejected any connection with feminism, they highlighted that, by participating in the MML women understood many issues related to gender, and said that the MML is fully integrated with the Argentinian women's movement. In light of these findings I suggest that in order to be able to capture the ambiguities of the relationship between women's movements of this type, and feminism, we need to adopt an approach that recognizes the dynamic nature of this relationship.
The performance of a pressure atomizer with a flow obstruction upstream of the nozzle

Year: 2009
Subjects: subject: Engineering, Mechanical.

description: The internal flow and the spray formed by a pressure atomizer with an orifice diameter of 1mm and a length to diameter ratio of 10 were studied at injection pressures between 70 and 5000 kPa. Obstructions to flow were also introduced inside the injector to examine their effect on the injector's performance. Visualization of the flow inside the injector indicated that the obstructions caused the flow to cavitate. However, even without any obstruction, cavitation occurred at injection pressures as low as 170 kPa. These results also showed that cavitation can occur in four different modes, depending on the mass flow rate of fuel through the nozzle and the type of obstruction. Images of the resulting spray indicated that the cavitation enhances atomization significantly. Single-component phase Doppler particle analysis and laser diffraction particle sizing were conducted 50 mm, 100mm and 150 mm downstream of the nozzle face to examine the size and velocity distributions of the droplets in the spray. These measurements indicated that for a given liquid flow rate the droplet size was not affected by the structure of the cavitation. Velocity measurements in the spray indicated that the cavitation produces a wider spray cone angle at lower mass flow rates.
A temporal and spatial bioinformatics study to analyze the genetic variability among SARS-CoV-2 genomes and design series of nested PCR primers for sensitive diagnosis
Creators: name: dewedar, doaa

description: During my professional diploma in bioinformatics, I engaged in a comprehensive study of the genomic variability among SARS-CoV-2 strains. Utilizing multiple sequence alignments and phylogenetic tree construction, we focused on conserved regions and extended our analysis to include genomic variability among SARS-CoV-1 and SARS-CoV-2, including fecal and oropharyngeal isolates. Our research involved an evolutionary comparison with related viral strains, leading to the identification of key SNPs and significant conclusions, such as the phylogenetic relationship of Australian sequences to the original Wuhan strain.

Additionally, we delved into the nested PCR primer design for virus detection. Our study revealed that relying solely on C.T. values may not suffice for diagnosing subclinical cases, emphasizing the reliability of PCR for virus detection. We pinpointed critical regions of the virus for molecular identification and recommended nested PCR for highly contaminated samples due to its high sensitivity. This research underscored the importance of well-designed primers and validated the utility of PCR in diagnostics.
Development of a Novel Strategy to Treat Spinal Muscular Atrophy

subject: Health Sciences, Immunology.

description: Spinal muscular atrophy (SMA) is an autosomal recessive disorder caused by reduced levels of the survival motor neuron (SMN) protein, which results in degeneration of motor neurons, leading to muscle weakness, and, ultimately, death. To provide an effective therapy for SMA, SMN expression must be restored in motor neurons. The goal of our research is to develop protein-based therapeutics for SMA. Protein transduction domain (PTD), from the human immunodeficiency virus-transactivator of transcription (HIV-TAT), mediates the transduction of any polypeptide to which they are fused. We produced bacterial expression cassettes of PTD-SMN. The PTD-SMN is able to transduce cells in vitro, reaching the nucleus and forming punctate structures similar to that of endogenous SMN. Internalization of PTD-SMN results in an increased nuclear-staining foci (gems) number. Importantly, this PTD-SMN co-localizes with coiled bodies, indicating PTD-SMN is able to localize to the correct region of the nucleus. However, we were unable to detect interaction of PTD-SMN with SMN known binding partners, suggesting that majority of PTD-SMN has low activity. Our results suggest that PTD-SMN produced from a prokaryotic source may be useful for SMA therapy, but optimization of protein production is required before this therapy can reach its full potential.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1997
Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis investigates the performance of a hybrid modulation scheme, combining subcarrier multiplexing and code division multiple access. This scheme may be useful in tomorrow's optical local area networks to take advantage of the capacity of optical fibers using commercially available optical technology. The application of subcarrier multiplexing to optical local networks has generated much interest recently, however it is sensitive to nonlinear distortion generated by the laser diodes used to transmit data over the optical network. Earlier research has indicated that combining code division multiple access with subcarrier multiplexing may provide improved performance. However the lasers' nonlinearity has not been specifically included in earlier research, due to the complexity of the analysis. In this thesis a simulation is used to evaluate the performance of the hybrid SCM-CDMA optical network. A custom program was written in the C language for this purpose. Preliminary results from the simulation program indicate that the performance of subcarrier multiplexed signals sent over an optical network may improve fairly substantially if code sequences are used to spread the bandwidth of information signals prior to optical transmission.

description: Background: Reintegration programs are commonly offered to former combatants and abductees to acquire civilian status and support services to reintegrate into post-conflict society. Among a group of young female abductees in northern Uganda, this study examined access to post-abduction reintegration programming and tested for between group differences in mental health status among young women who had accessed reintegration programming compared to those who self-reintegrated. Methods This cross-sectional study analysed interviews from 129 young women who had previously been abducted by the Lords Resistance Army (LRA). Data was collected between June 2011-January 2012. Interviews collected information on abduction-related experiences including age and year of abduction, manner of departure, and reintegration status. Participants were coded as ‘reintegrated’ if they reported ≥1 of the following reintegration programs: traditional cleansing ceremony, received an amnesty certificate, reinsertion package, or had gone to a reception centre. A t-test was used to measure mean differences in depression and anxiety measured by the Acholi Psychosocial Assessment Instrument (APAI) to determine if abductees who participated in a reintegration program had different mental status from those who self-reintegrated. Results From 129 young abductees, 56 (43.4%) had participated in a reintegration program. Participants had been abducted between 1988–2010 for an average length of one year, the median age of abduction was 13 years (IQR:11–14) with escaping (76.6%), being released (15.6%), and rescued (7.0%) being the most common manner of departure from the LRA. Traditional cleansing ceremonies (67.8%) were the most commonly accessed support followed by receiving amnesty (37.5%), going to a reception centre (28.6%) or receiving a reinsertion package (12.5%). Between group comparisons indicated that the mental health status of abductees who accessed ≥1 reintegration program were not significantly different from those who self-reintegrated (p > 0.05). Conclusions Over 40% of female abductees in this sample had accessed a reintegration program, however significant differences in mental health were not observed between those who accessed a reintegration program and those who self-reintegrated. The successful reintegration of combatants and abductees into their recipient community is a complex process and these results support the need for gender-specific services and ongoing evaluation of reintegration programming.
The failure of the international system of protection of human rights: Ethnic and national minority rights.
Creators: name: Komenda, Ryszard D.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Political Science, International Law and Relations.

description: The primary objective of this work is to examine how effective international mechanisms for the protection of minorities are in resolving ethnic conflicts. Often violent, these conflicts threaten the territorial integrity and stability of states; yet in most cases, states oppose implementation of measures to protect minorities. The denial of minority rights is probably the single most important factor in the escalation of ethnic conflicts. This work surveys existing international mechanisms for minority protection and explores the reasons why an effective system for protection of minority rights has yet to be established. It will attempt to answer the following question: Why has the United Nations system failed to deliver effective protection of minorities? The thesis explores changing attitudes towards minorities in the light of theory of international human rights law. Special attention will be paid to the emerging international phenomenon of non-governmental organizations.
Physical and electrochemical basis of induction of reversibility in manganese dioxide reduction and reoxidation.
Creators: name: Qu, Deyang.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1994
Subjects: subject: Chemistry, Physical.

description: "Chemically Modified" (CM) rechargeable MnO$\sb2$ cathode materials have been prepared, based on patents issued to Ford. The reaction mechanisms of the discharge and recharge of these materials have been extensively studied in the present work and compared with behaviour at Blank MnO$\sb2$ (without Bi) and regular $\gamma$-MnO$\sb2,$ by various experimental techniques including classical electrochemical methods, as well as a newly developed in-situ uv-visible spectro-electrochemical method and a new in-situ X-ray absorption (XAS) electrochemical procedure. The roles of the soluble Mn(+III) species and Bi dopants in the discharge and recharge processes have been investigated in some detail. Firstly, the presence of Bi(III) favours the formation of soluble Mn(OH)$\sb6\sp{3-}$ species in both the processes of discharge and recharge and, secondly, it appears to work as a "catalyst" for the steps involved in further reduction of Mn(OH)$\sb6\sp{3-}$ species to Mn(OH)$\sb2$ in discharge, and re-oxidation of Mn(OH)$\sb2$ to MnO$\sb2$ on recharge. Based on the optical absorbance measurements, an heterogenous mechanism in which the soluble Mn(OH)$\sb6\sp{3-}$ intermediate is involved, is directly indicated as being the preferred pathway at CM MnO$\sb2$ and operates in parallel with the so-called homogenous mechanism in both the processes of reduction of MnO$\sb2$ and re-oxidation of reduced MnO$\sb2$ materials. Thus, from the soluble Mn(OH)$\sb6\sp{3-}$ species, either Mn(OH)$\sb2$ can be deposited, on reduction, or MnO$\sb2$ re-formed on re-oxidation, on the porous electrode matrix at favourable and practically significant current-densities. The CM MnO$\sb2$ is then rechargeable over a practically useable voltage range and, importantly, over the 2-electron charge capacity. On account of the preferred heterogeneous pathway at CM MnO$\sb2,$ high (up to 6C) discharge rates can be realized at a remarkably constant plateau voltage, independent of discharge rate. In the light of the mechanism studies, the electrochemical performance of the CM MnO$\sb2$ has been studied. The CM MnO$\sb2$ cathodes were characterized by (a) good multiple rechargeability, (b) high energy and power densities, (c) achievement of high charging/discharging rates at a surprisingly constant working voltage and (d) low cost. Use of an ion-selective separator enables the CM MnO$\sb2$ to be used in a secondary alkaline MnO$\sb2$ battery system with a Zn anode, and an appreciable cycle-life to be realized which is not possible if ZnO$\sb2\sp{2-}$ ions diffuse to the MnO$\sb2$ cathode. These characteristics make the secondary CM MnO$\sb2$/Zn battery system a promising candidate for electric vehicle applications and also for many other market niches currently occupied by Ni-Cd secondary and MnO$\sb2$/Zn primary cells in the consumer market.

Year: 2016

description: Background: Measurement-unit conflicts are a perennial problem in integrative research domains such as clinical meta-analysis. As multi-national collaborations grow, as new measurement instruments appear, and as Linked Open Data infrastructures become increasingly pervasive, the number of such conflicts will similarly increase. Methods: We propose a generic approach to the problem of (a) encoding measurement units in datasets in a machine-readable manner, (b) detecting when a dataset contained mixtures of measurement units, and (c) automatically converting any conflicting units into a desired unit, as defined for a given study. Results: We utilized existing ontologies and standards for scientific data representation, measurement unit definition, and data manipulation to build a simple and flexible Semantic Web Service-based approach to measurement-unit harmonization. A cardiovascular patient cohort in which clinical measurements were recorded in a number of different units (e.g., mmHg and cmHg for blood pressure) was automatically classified into a number of clinical phenotypes, semantically defined using different measurement units. Conclusions: We demonstrate that through a combination of semantic standards and frameworks, unit integration problems can be automatically detected and resolved.

description: As police forces are information intensive organisations, the use of advanced Information Systems in policing has led to the transformation of the social and the organisational life in forces. Nevertheless, the results of a pilot study conducted after four years of the roll out of mobile Kelvin devices in a medium-sized Constabulary in the UK have revealed officers’ resistance to using the full range of functionalities offered by these devices. The Kelvin devices’ initial training did not accommodate for differences in officers’ IT skills, experiences, roles, work contexts and police culture (ensuring the existence of a good-fit between all these factors). Hence, officers were unable to efficiently appropriate the Kelvin devices’ functionalities in different contexts and to various tasks. Therefore, guided by the data collected from the pilot study, a Fit and Appropriation Model for training (FAMT) is posited. FAMT aims to rectify the causes of officers’ resistance by not only creating a learning environment that bridges the gap in technical knowledge and skills but also enables learners to use their work experiences to link technology features to various tasks and contexts. The impact of using FAMT on the learning process sheds light on the key deteriminants of delivering effective technology training in organisations. The findings of the study delineate fundamental super-user’ characteristics and police culture aspects that can influence the learning process during training. Furthermore, the study highlights the significant role of providing IT support during technology training. This role should not be underestimated by mangers as it impacts profoundly on the effectiveness of female learners’ technology sense-making. Besides, incorporating collaborative training methods into FAMT have enhanced learners’ ability to extend the use of features to different contexts. Therefore, using FAMT has been perceived by officers as an effective training method that facilitates a personalised technology training and extends their knowledge about useful features in their Kelvin devices.
title: Behavioural Subtyping in Process Algebra

Publisher: name: University of Kent

description: Subtyping relations embody a notion of substitutability, and are an important tool in formal methods. The downward simulation relation is well-known and widely used as a subtyping and refinement relation for state-based approaches, but there is no single relation which is widely accepted to be the subtyping relation for the behavioural setting; however, there are several candidate relations. Developments such as the multi-viewpoint specification method of RM-ODP encourage the use of several different formal methods in a single project. Thus, it becomes important to obtain implementations of a single notion of subtyping in several different paradigms. In this thesis, we attempt to find a process algebraic relation which corresponds to the state-based subtyping relation, downward simulation. While trying to achieve this, we define a translation between a state-based notation and a process algebra, and we uncover some of the similarities and differences between these two specification paradigms. In particular, we investigate the meaning of undefined behaviour in each setting. When a state-based specification does not define an operation, the intent is that the system's behaviour is unspecified (not well-defined) if that operation is invoked. In a process algebra with refusals semantics, however, a process is implicitly specified to refuse any action it is not specified to accept, and such a refusal constitutes well-defined behaviour. As part of our translation, we devise a method of representing the unspecified behaviour of the state-based world in a process definition. Finally, we use our translation to prove that the presence of subtyping between a pair of state-based specifications implies reduction between their LOTOS translations, but that the presence of reduction does not imply subtyping. We conclude that reduction itself does not correspond to state-based subtyping, but that any relation which does must be based on a stronger semantics than reduction, such as bisimulation semantics.
Étude des variations climatiques (1921-1990) des Prairies canadiennes à partir de la classification de Köppen : une application des SIG dans l'étude des changements environnementaux.

description: The primary objective of this thesis was to study climatic variations that occurred in the Grassland Ecoclimatic Province (Canadian Prairies), between 1921 and 1990, using a geographic information system (GIS). DBASE IV was used to establish the Koppen classification. The annual classification showed important climatic variations within the study period. No station could be associated to only one climatic classification, but to many categories. For example, the climate for Medicine Hat cannot be considered as purely semiarid (31 years classified as BSk) because it also has many years classified as Dvb (12) and Dsb (11). The climatic maps, representing each decade, showed much more information, concerning the spatial variations of the Prairies climate. The 1981-90 period had the most important surface classified as semiarid (BSk), this classification representing 7.73% of the total area covered by this study (579 800 km$\sp2$). This semiarid area, generally situated around Medicine Hat, completely disappeared if not almost between 1931 and 60. The 1931-40 map did not show the presence of very dry conditions reported for the Prairies during the Dust Bowl period (1936-38). Yearly maps created for this important dry spell, agreed with some of the information published by Phillips (1990) and Jones (1991), concerning the areas affected by the Dust Bowl droughts. However, the map for 1936 showed no station classified as BSk, despite the fact that it was very dry that year. The use of the Koppen's classification permitted a climatic analysis based on critical thresholds of temperatures and precipitation, which favor or limit vegetation growth. The use of a GIS, helped to easily process large amounts of data, in order to create climatic maps according to this climatic classification. (Abstract shortened by UMI.)

description: This study empirically investigates the structural constraints influencing the productivity of Persian compounding processes, using a corpus derived from the Persian Linguistic Database (PLDB). It examines phonological, morphological, syntactic, and semantic factors limiting the formation of new compounds. In this study, productivity refers to the degree to which a morphological process is used to create new words in a given language. The findings reveal an inverse relationship between productivity and the number of constraints applied: as constraints increase, productivity declines. Phonological factors include syllabic and phonological structure of the word, while morphological constraints relate to the category, structure, and affixation of the base. Syntactically, productivity depends on category combinations and subcategorization frames. For example, bases like /ʔāb/ (water) and /por/ (full) demonstrate higher combinatory potential compared to less flexible bases such as /pir/ (old) or /šanbe/ (Saturday). In the semantic domain, transparency and compositionality play crucial roles. Compounds with meanings derivable from their components show higher productivity, whereas opaque or metaphorical compounds stem from less productive processes. This study highlights the interaction of phonological, morphological, syntactic, and semantic
factors in shaping Persian compound formation.

The contact phenomena found in Classical Arabic and Modern Standard Arabic are therefore often the result of imposition. Cases of borrowing are significantly rarer, and mainly found in the lexical sphere of the language.
Sociocultural pertinence in translation: Dario Fo's "Mistero buffo" and its Quebecois transfiguration.

description: The aim of this thesis is to illustrate, through a case-study, the sociohistorical and ideological constraints to which the activity of translation is subject. Underlying the source text that was chosen--Dario Fo's Mistero buffo--there is one particular ideologeme which can be summed up as follows: 'the people have always been exploited'. In Michel Tremblay's 1973 translation, this ideologeme is converted into a different ideologeme: 'the Quebecois have always been exploited'. In order to shed light on this radical transformation, both plays are first situated in their sociocultural contexts and then analysed in terms of the social discourse that prevailed at the time of their reception in Italian and Quebecois society respectively. In this descriptive study the concept of 'pertinence'--as opposed to the translation's aesthetic merit per se--is employed as the chief criterion for interpreting translational shifts; the pattern of these shifts indicates that they are motivated principally by Tremblay's desire to make Mistero buffo correspond to the target audience's horizon of expectations.

description: The mechanism by which the atypical neuroleptic clozapine is able to relieve the symptoms of schizophrenia without causing extrapyramidal side effects that are characteristic of most other antipsychotic drugs is unclear. c-fos is a proto-oncogene that encodes a 55 kDa phosphoprotein, Fos, which is thought to be an activity marker in the central nervous system. Recently, it has been shown that clozapine and haloperidol produce distinct patterns of increased c-fos expression in the rat forebrain. Haloperidol induces Fos-like immunoreactivity (FLI) in the nucleus accumbens, dorsolateral striatum and lateral septal nucleus, whereas clozapine preferentially increases in FLI in limbic structures such as the prefrontal cortex, nucleus accumbens, mediolateral striatum and lateral septal nucleus. These findings suggest that clozapine's unique therapeutic profile may be related to its failure to induce FLI in the striatum as well as its idiosyncratic actions in the medial prefrontal cortex. Given the significant clinical implications of these results, the present study attempted to identify these receptors which mediate the different effects of clozapine and haloperidol on c-fos expression.

description: Engineering construction in cold regions is greatly effected by the environment. The type of structure, its design, its erection and its operation and maintenance are all influenced by the surrounding meteorological conditions. Another consideration is of course the site on which the construction is to be erected. Before construction one has to determine, above others, how deep the soil below the surface is frozen and this requires heat transfer analysis on that particular site. In this thesis heat flux for thirty-two sites are considered. These sites are chosen since their n-factors and soil properties are known experimentally. With weather data like air-temperature, dew-point temperature, cloud cover and wind speed supplied by the United States National Oceanic and Atmospheric Administration (NOAA), it is possible to calculate the net shortwave and longwave radiation, and the convective heat flux at the surface. For two of the sites; Fairbanks, Alaska and Boston, Massachussetts, data on radiation are available and they can be used to check the accuracy of the results obtained using the existing equations. For these two sites empirical relationships on the effect of cloud cover on shortwave and longwave radiation can also be obtained. With the calculation of seasonal heat fluxes and the known soil properties it is possible to calculate the air and surface indexes, the n-factor, and finally by using appropriate parameters, obtain an empirical relationship between the surface and the air indexes. It will also be seen how close the calculated results agree with the theory.

description: As of 2024, Rwanda has achieved an installed power capacity of 400.1 MW, with an available capacity of 396.7 MW. In June 2024, the maximum peak demand reached 233.7 MW, while the minimum peak was 195.6 MW. The challenge for the utility is how to effectively manage generation in relation to demand and meet Independent Power Producers (IPP) obligations. One potential solution lies in maximizing electricity consumption among Productive Use of Electricity (PUEs) consumers. However, limited data hampers the ability to fully explore this option. Therefore, a study on potential consumers, including productive users and all non-residential customers, has been proposed. To address this challenge effectively, a comprehensive database and a robust data governance framework are crucial. The proposed database schema will catalog productive user energy usage, track consumption across various consumer segments, and this will provide a data-driven approach to balancing supply and demand.
Modeling the electric field and natural environment of weakly electric fish

description: Weakly electric fish use a unique sensory modality in order to help them communicate, navigate and find prey. These fish emit electric discharges that are monitored by electroreceptors located in the fish's skin. Surrounding objects perturb these baseline transdermal potentials and create electric images. The study of these images has led to a better understanding of general sensory processing principles; however, many aspects of these fish's natural electrosensory environment remain unknown. To this end, a two-dimensional finite element model of Apteronotus leptorhynchus was created. Using this model, we suggest new ways by which electric fish are able to locate objects and propose that it is possible for these fish to extract useful information from their environment using their natural scanning behaviour. Our results also reveal important limitations in standard experimental paradigms that aim to mimic the effects of conspecifics. Alternative paradigms that will enable more realistic stimulation are suggested.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Background: Essential genes are critical for the development of all organisms and are associated with many human diseases. These genes have been a difficult category to study prior to the availability of balanced lethal strains. Despite the power of targeted mutagenesis, there are limitations in identifying mutations in essential genes. In this paper, we describe the identification of coding regions for essential genes mutated using forward genetic screens in Caenorhabditis elegans. The lethal mutations described here were isolated and maintained by a wild-type allele on a rescuing duplication. Results We applied whole genome sequencing to identify the causative molecular lesion resulting in lethality in existing C. elegans mutant strains. These strains are balanced and can be easily maintained for subsequent characterization. Our method can be effectively used to analyze mutations in a large number of essential genes. We describe here the identification of 64 essential genes in a region of chromosome I covered by the duplication sDp2. Of these, 42 are nonsense mutations, six are splice signal mutations, one deletion, and 15 are non-synonymous mutations. Many of the essential genes in this region function in cell cycle, transcriptional regulation, and RNA processing. Conclusions The essential genes identified here are represented by mutant strains, many of which have more than one mutant allele. The genetic resource can be utilized to further our understanding of essential gene function and will be applicable to the study of C. elegans development, conserved cellular function, and ultimately lead to improved human health.
